BACKGROUND/OBJECTIVES: The purpose of the study was to investigate the relationship between household food insecurity and nutritional status of children in low-income households. A cross sectional study involved a survey of households (n = 223) receiving the financial assistance. SUBJECTS/METHODS: Eligible mothers that fulfilled the inclusion criteria such as non-pregnant, non-lactating mothers, aged 18 to 55 years with their youngest children aged 2 to 12 years, were purposively selected. The Radimer/Cornell hunger and food-insecurity instrument was administered and children's height and weight were measured. RESULTS: About 16.1% of the households were food secure, while 83.9% experienced some kind of food insecurity. Out of food insecure category, 29.6% households were food insecure, 19.3% women were individual food insecure and 35.0% fell into the child hunger category. Education of the mother (P = 0.047), household size (P = 0.024), number of children (P = 0.024), number of children going to school (P = 0.048), total monthly income (P < 0.001), income per capital (P < 0.001), number of household members contributing to the income (P = 0.018) and food expenditure (P = 0.006) were significant risk factors for household food insecurity. The prevalence of underweight, stunting and wasting in children were 61.0%, 61.4% and 30.6% respectively. Based on multinomial logistic regression, children in food-insecure households were 2.15 times more likely to be underweight and three times to be stunted than children in the food-secure households. CONCLUSIONS: The findings suggest that household food insecurity is associated with the nutritional status of the children in the rural area of Northeastern Peninsular Malaysia.

This study evaluated the satisfaction and healthy eating index of nutrition-plus program providing nutritional supplements to pregnancy, lactating women, infant and children. This program was carried out at Public Healthcare Center, Seodaemun-gu in Seoul from February 2014 to June 2014. The subject selected among applicants for low income family financing of the government included 159 subjects. There was no statistically significant difference for degree of satisfaction with supplementary food by age, but the degree tends to get higher at lower age. Degree of satisfaction with supplementary food by the duration for participation was shown higher as the duration gets longer. For questions of 'Do you check nutrition label?' and 'Do you preserve food as described at food label?' in healthy eating index evaluation, the scores appeared higher at younger age group as they check the nutrition label more. Also as the duration for participation gets longer, the scores appeared higher which can be interpreted as effect of nutrition education from Nutrition-Plus. Frequency of having breakfast gets lower at higher age of subjects. And it gets higher as the duration for participation gets longer even though that there's no difference between '3 to 4 months' and '5 to 8 months' of the duration of participation. For evaluation of food security in recent 1 year, 86.8% of subjects responded 'Food sufficiency' and 'Enough but not always the kinds of food we want', and there is no difference by age and the duration of participation. As a result of this research, it is shown that the subjects of nutrition support project are relatively satisfied with the support. And healthy eating index gets improved as the duration of participation gets longer which can be considered as effect of nutrition education. It seems to be necessary to keep nutrition education as well as food support so to perform food life education on appropriate purchase and consumption of food.

This study was carried out to investigate the lactation and weaning practice of infants and their mothers' attitude on infant nutrition. We interviewed 152 mothers in three pediatric clinics located in Sokcho city. From this survey, $76.3\%$ of infants was fed colostrum milk during first one week of life. During the first 4 months, $31.6\%$ of infants was fed breast-milk, while $42.8\%$ of them was fed bottled-milk. More housewives fed their babies with breast milk than the working mothers. Infants ate first weaning food at 5.73$\pm$1.86 months of life. Highly educated mothers showed positive response to the questionnaire : Breast-feeding is good for baby but it requires mother's sacrifice, and Breast-feeding may ruin the good shape of mothers. Highly income mothers responded negatively to the statement : Breast-feeding is not a must for infants since bottled-milk is a good substitution for breast-milk. Comparing with the mothers whose income was about 1 -2 million won per month, with ones who got paid less than 1 million won per month the former responded positively to : Breast-feeding is good for baby but it requires mother's sacrifice. Mothers recognized the importance of weaning in the following order : Supply of nutrition, Enforcement of digestion and absorption capability, Variety of taste, Disease prevention, Development of self-reliance, and Development of baby tooth. To improve the infants' nutritional status, education program on infant nutrition should be organized and run for the pregnant and lactating women in obstetrician and pediatric clinics and through the mass media as well.

This study measured variables influencing the breast feeding patterns of lactating mothers over a 40 day period In 1993 in the Jeonla area. The Methodology used was a questionnaire covering 92 items based on statistical discriminant analysis. The results were as follows : The successful group was measured against the unsuccessful group over a 4month lactation period ; The successful group was measured over a 4month lactation period ; the unsuccessful less than 4month lactation period. Principal factor analysis was used to generate comparative data factors which were ; 1) nonunderstanding of mother's breast feeding, 2) physical and psychological stress, 3) insufficient milk supply, 4) mother's negative acceptance of baby, 5) lack of spousal support, 6) sore nipple and breast pain, 7) baby's negative acceptance, 8) lack of familial support, 9) baby's diarrhea and watery milk. Discriminant statistical analysis of sever factors included ; 1) insufficient milk supply 2) sore nipple and breast pain, 3) pre-natal planning of breast feeding method, 4) mother's occupation 5) breast feeding method of previous infant, 6) nipple type, and 7) infant birth order. This analysis predicted a 78.9% successful breast feeding. Criterion correlation analysis revealed ; D=-1.780+.165$\times$(Fac3)+.135$\times$(Fac6)+.927$\times$(prenatal planning of breast feeding method)+.900$\times$(mother's occupation)+.675$\times$ (breast feeding method of previous infant)+1.0l4$\times$(nipple type)+.378$\times$(infant birth order). We classified the unsuccessful group as more than .63937 and the successful group less than -.82742 of the D value obtained from the above criterion correlation in order to check the success or the non-success of breast feeding mothers. The rate of correct classification of the grouped cases employing a statistical discriminant analysis was significantly improved to 78.9% when these cases were compared with the actual grouped classification.

Objectives: This study was conducted to estimate the dietary iodine intake of Koreans by a Total Diet Study (TDS) which provides 'closer-to-real' estimates of exposure to hazardous materials and nutrients through an analysis of table-ready (cooked) samples of foods. Methods: Dietary intake data from 2013-2017 Korea National Health and Nutrition Examination Survey (KNHANES) was used to select representative foods (RFs) for iodine analysis. A total of 115 RFs were selected and 158 'RF × cooking method-combination' pairs were derived by pairing each RF to corresponding cooking method(s) used more frequently. RFs were collected from 9 mega-markets in 9 metropolitan cities nationwide and mixed into composites prior to cooking preparation to a 'table ready' state for iodine analysis by inductively coupled plasma mass spectrometry. Iodine intake of Koreans was estimated based on the food intake data of the 2016-2018 KNHANES. Results: High iodine content was detected in seaweeds such as sea mustard and kelp. The mean iodine intake/capita/day was 418.4 ㎍ and the median value was 129.0 ㎍. Seaweeds contributed to 77.4% of the total iodine intake and the contribution by food item was as follows: sea mustard (44.0%), kelp (20.4%), laver (13.1%), milk (3.9%), egg (3.5%). Compared to the Dietary Reference Intakes for Koreans 2020, the proportion of people with iodine intake exceeding the tolerable upper intake level or below the estimated average requirement was high in the physiologically vulnerable groups (infants, children, pregnant women, and lactating women). Conclusions: The results, drawn from a TDS, are regarded closer to real estimates for iodine intake of Koreans compared with values in existing literature, which were based on a very limited variety of foods. On the other hand, it seems necessary to seek out solutions for the problematic iodine intake among physiologically vulnerable groups through in-depth analyses on food intake data collected with significant scale & quality.

2020 한국인 영양소 섭취기준에서 탄수화물은 만성질환 예방을 위한 섭취기준으로 총 에너지 섭취량에 대한 탄수화물로부터의 에너지 섭취비율인 에너지적정비율을 1세 이후 모든 연령에서 55-65%로설정하였다. 그리고 2020년에 처음으로 탄수화물의 평균필요량과 권장섭취량을 설정하였다. 인체의 탄수화물 필요량은 뇌에서 하루에 소비되는 포도당량과 케톤체 생성이 나타나지 않는 양을 기준으로 1세 이후 모든 연령에서 1일 100 g을 설정하고, 권장섭취량은 15% 변이계수를 사용하여 두 배의 변이계수를 더한 130 g/일로 설정하였다. 탄수화물의 평균필요량은 최소필요량의 개념이지 에너지원으로서 적절한 섭취량에 대한 개념은 아니므로 탄수화물의 영양소섭취상태를 평가할 경우에는 평균필요량이나 권장섭취량에 비교하는 것은 적절하지 않고, 에너지적정비율을 활용하여 탄수화물로부터의 에너지 섭취비율의 적절성을 평가하는 것이 적절하다. 탄수화물은 에너지 적정비율범위에서 섭취할 때 만성질환의 위험을 낮출 수 있으며, 이를 탄수화물의 양뿐만 아니라 급원도 고려하는 식생활에 활용해야 할 것이다.

엽산은 비타민 B군에 속하는 수용성 비타민으로, 핵산 합성과 아미노산 대사에서 단일탄소를 전달해 주는 반응의 조효소 역할을 한다. 엽산은 새로운 세포가 형성되어 성장하는 임신기와 성장기에 매우 중요한 영양소이며, 여성의 임신 전 적절한 엽산 영양상태는 신경관 결손증을 예방한다고 알려져 있다. 이 외에도 엽산 섭취 부족은 빈혈, 고호모시스테인혈증, 심혈관질환, 암, 인지 장애, 우울증 등 다양한 질병과도 관련이 있다고 보고되어, 엽산은 전 생애주기 동안 건강을 유지하기 위해 충분히 섭취해야 하는 영양소이다. 본 연구에서는 2020 한국인 엽산 섭취기준의 개정 근거를 살펴보고, 국민건강영양조사로부터 엽산 섭취량과 혈청 엽산 농도를 성별, 연령대별로 분석하였으며, 향후 엽산 섭취기준 개정에 참고할 만한 내용을 제언하였다. 표준체중의 변경에 따라 영아 후기의 충분섭취량과 15-18세의 평균필요량이 2015년과 달리 변경되었으나, 권장섭취량과 상한섭취량에는 변화가 없었다. 2016-2018년 국민건강영양조사 결과에서 대부분의 연령에서 엽산 섭취량은 권장섭취량에 미치지 못하였으며 특히 15-29세 여성의 섭취량이 권장섭취량 대비 매우 낮았다. 임신부와 수유부의 엽산 섭취량도 권장섭취량 대비 60% 이하로 낮았으나, 혈액수준은 다른 연령층에 비해 높아 보충제를 섭취한 결과로 보인다. 앞으로 국민건강영양조사에서 보충제 섭취량도 조사해야 할 것이며, 엽산의 섭취량 평가를 위해서는 생식품, 조리된 식품, 강화식품 중의 엽산 함량에 대한 DB가 구축되어야 할 것이다. 또한 혈청 엽산 뿐 아니라 적혈구 엽산 농도와 혈장 호모시스테인 농도도 분석할 필요가 있으며, 분석방법에 대한 질 관리가 필요하다.
